Sort by custom field using Jira's API

Question

I am trying to use Jira's API to get back data. Everything works fine unless I try to sort by a custom field. If I sort by a default field, it's fine, but if I sort by a custom field, I get this error:

 {"errorMessages":["Not able to sort using field 'customfield_11200'."],"errors":{}}

Here is the API call:

search?jql=project+IN+(TEST)+order+by+customfield_11200+asc&fields=id,key,priority,summary,issuetype,status,customfield_11100,customfield_11200&maxResults=3&startAt=0

Any ideas on why you can't sort on a custom field?

Answer 1

so, it turns out that Jira's api expects the field to be formatted like this: cf[11200]
